ELECTRON MINIACCELERATOR ON THE BASE OF TESLA TRANSFORMER FOR THE BEAM OF CHARGED PARTICLES NONDESTRUCTIVE TESTINGS

The electron miniaccelerator on the base of Tesla - transformer for the beam of charged particles nondestructive testing with operating voltage up to 200 kV, half-wave duration 4 mks and diagnostic beam current within few mA is described. The primary circuit is switched by IGBT-module. The gun control and filament circuit power supply (impregnated cathode with 1.2 mm diameter) are performed through high frequency isolated transformer. The accelerating tube is performed f rom sectional welded metal ceramics insulator (ceramics 22HS with diameter 95/85 mm). The accelerators test results are presented.
